To all whom it may concern: a a

Be it known that we, CORTLAND W. DAVIS and FRANK R. SUNDERLIN, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inInsulated Vitreous Receptacles; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

Our invention relates to insulated vitreous receptacles, objectsthereof. being to render such receptacles immune, as far as possible,from external thermal influences, and also to shield them from blows andshocks which are incident to transportation and use. I

Referring to the drawings I Figure 1 shows a vertical sectionof'thereceptacle, portions thereof being shown in elevation.

Fig. 2 is a plan view of a cover for the vitreous portion of thereceptacle.

Fig. 3 is a section taken on the line 2-2 of Flg. 2.

Fig. 4 is a large detailed section of an upper portion of thereceptacle.

1 is a non-vitreous protective jacket, preferably made of sheet metal,rolled and bent into cylindrical form, the edges of the sheet beingoverlapped, riveted and soldered together in the usual manner;

2 is a vitreous container, between which and the protective jacket is-aspace for the reception of a non-heat conducting filling, 3, which ispreferably granulated cork,-although it may be composed of any suitableheat insulating material. The exterior surface of the containeris-preferably silvered.

Separation of the jacket 1 and container 2 is maintained by braces, 4,4, the braces? being set diagonally, as shown, to assist in taking theend thrust .of the container. It will be understood that the filling ofmaterial is tightly packed in the space between the jacket and thecontainer, so as to prevent relative motions of the parts.

5 is a seat fora brace 4,.secured to the inner wall of the jacket 1' byrivets 5". Screws 5 extending through a hole 5 in the seat 5 and intothe brace 4 secure said brace in fixed relation to said jacket. The wallof the jacket 1 is provided with .upper corrugations 6, and lowercorrugations 6 which, in a great measure, prevent the filling 3 frommoving longitudinally in the annular space between the jacket 1 and thecontainer 2.

The jacket 1 is provided with a bottom 7 having a downwardly extendingflange 7 riveted and hermeticall sealed to the lower edge of the jacket1 wh ch constitutes a support for the receptacle.

A reinforcing ring 8 encircles the lower end of the jacket 1.

9 is an annular yielding shock insulating diaphragm, 4 preferably madeof copper, soldered at its upper end to the inner wall of the jacket 1.

a suitable bonding agent and preferably made of any non-corrosive metal,such as brass. .This collar has, an inturned flange v The container 2 ispror' -vided with a collar 10, secured theretoby U 10 which rests onthetop edge of the container 2. This collar 10 is also provided with anoutwardly extending sloping flange 10", forming a groove for solder andoverlapped by the inner edge of the diaphragm dered together at theiroverlapping parts.

The shock insulating diaphragm 9 is provided with a cylindrical bodyportion 9, and an outwardly extending flange 9 having a turned-up edge 9which extends to edge 9 is to provide a large contact surface for thesolder, and to leave a space 9 through which shocks administered fromthe outside will not be transmitted to the main bod of the diaphragm 9and to other parts of t e constructlon. It will be observed that 9, thediaphragm and the collar belng sol- 4 the top of the jacket 1. Theobjects of the the general shape of'the diaphragm 9 is such 4 as torovide a depression 9 which extends entire y around the neck of thevitreous container to prevent externally administered shocks fromreaching said neck. The use of copper in the construction of thediaphragm 9 adds further security to the Vlt',

reous container, it having been found that soft metal, such as copper,will yield without transmitting shocks. Copper is, furthermore, usefulin this relation inasmuch as it i is only slightly corrodible and iseasy to kee lphclean.

e device is" rovided with a bail 11, the

inturned ends which oscillate in holes 12 in the body of the jacket 1,said inturned ends being provided inside said jacket Wltlt perforations11, through which extend cotter pins 11 Cups 13 soldered to the innerwall of the jacket 1 inclose the inwardly protruding ends of the bail.

The container 2 is provided with a'cover i 14, consisting in the main ofa circular body of cork 14 adapted to fit within and tightly close theneck of the container 2. 14 is a protective cap covering the entireupper surface of the cover '14: and extending downward around the marginof said cover to form a fiange 14. The cap is secured in position on thecover by bolts 15 having nuts 15 resting in depressions 14 of the cover,these depressions being filled with cork plugs 16. While we prefer corkas the ma.- terial for the cover, it will be understood J that othersubstances which are poor conductors of heat may be used instead ofcork.

The fiange 14 may be of such size as to constitute a shoulder for thecover 14, whereby said cover may bear upon the top edge of the neck ofthe container, or upon the inwardly turned flange 10 of the collar 10.

The cover 1 1 is provided with a swiveled cross bar 17 having downwardlyturned ends 17 which are provided with inwardly extending tapering lugs17 which may be formed by bending inward a portion of the metal.

The collar 10 is provided with a series of outstanding rivets 10extending through and riveted inside said collar. These rivets arepositioned to engage the tapered lugs 17 of the cross bar 17. to therebylock the cover it in position on the container 2. The cross bar 17 isswiveled on one of the bolts 15 which carries on a screw threadedportion thereof a nut 15 spaced sufiiclently far from the head of thebolt to allow the cross bar to during its oscillations.

turn freely on said bolt as a pivot. The cap 14* has a raised center 14which prevents of the collar and the annulus 10 and 9 will be melted, soas to free the container and allow it to be withdrawn through the openbottom ofthe jacket 1 and anew container inserted in lieu thereof.

The jacket 1 is encircled by a protecting ring 8 secured thereto byrivets.

The entirereceptacle is closed by a cover 18 having a flange 18" fittinsnu ly over the reinforcing ring 8*. The e geo? this flange 18 isprovided with a bead 18 with which a pivoted clamp 19 is adapted toengage, this clamp 19 being provided with a groove' 19 adapted to,fitsaid head 18". The pivot of the-clamp 19 is formed by rivets 20'fixed inthe jacket 1 and loosel fitting openings 19 in thelower end' of tlieclamp'. A headed bolt 21 fixedly secured inthe reinforcing ring 8,threadedat its outer end and extending through an aperture 19, isengaged by a I thumb nut 22, by means of which said clamp 19 may beforced into engagement with the bead 18 The thumb nut has a depression19 in which the head of the retaining bolt 21 moves. Several of theseclamps 19'may be employed, as desired.
